Abstract

Sucralfate preparation produced by melt granulating a mixture of a comminuted sucralfate powder and a water-soluble low-melting point wax, as well as a process for producing a sucralfate preparation comprising the steps of comminuting dry sucralfate into fine particles, mixing the finely divided particles with a water-soluble low-melting point wax and heating the mixture such that the wax is melted to effect melt (adhesion) granulation of the finely divided sucralfate particles are disclosed. Compared to conventional sucralfate preparations, the thus produced sucralfate preparation has a small dispersed particle size, exhibits high capability for binding to plasma proteins and thereby achieves marked improvements in administrability and protein binding capability.
